我需要一些帮助才能在Ubuntu 14.10 64位中运行此代码。我用ubuntu 14.04 32位编译了这段代码并且工作正常......但是如果我把它转换成64位（相同的PC，另一个分区）14.10，我就无法创建一个Opengl 3.3上下文。我不知道问题是什么。
这里是mi代码glxwindow.h

这是glxinfo报告（好像一切都好）：
fabian@fabian-ThinkPad-L440:~$ glxinfo | grep "OpenGL"
OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) Haswell Mobile
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.0-devel (git-ba35393 2015-04-04 utopic-oibaf-ppa)
OpenGL core profile shading language version string: 3.30
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 3.0 Mesa 10.6.0-devel (git-ba35393 2015-04-04 utopic-oibaf-ppa)
OpenGL shading language version string: 1.30

OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.0 Mesa 10.6.0-devel (git-ba35393 2015-04-04 utopic-oibaf-ppa)

OpenGL ES profile extensions:
答案 0 :(得分：2)
您在此处请求3.3 兼容性个人资料：
int context_attribs[] =
{
GLX_CONTEXT_MAJOR_VERSION_ARB, 3,
GLX_CONTEXT_MINOR_VERSION_ARB, 3,
GLX_CONTEXT_PROFILE_MASK_ARB , GLX_CONTEXT_COMPATIBILITY_PROFILE_BIT_ARB,
//GLX_CONTEXT_FLAGS_ARB , GLX_CONTEXT_FORWARD_COMPATIBLE_BIT_ARB,
None
};
Mesa does not support the compatibility profile:
OpenGL核心和兼容性上下文支持
只有Core支持OpenGL 3.1及更高版本 轮廓。没有计划支持GL_ARB_compatibility。最后 支持所有弃用功能的OpenGL版本为3.0。一些 后面的GL功能在3.0上下文中作为扩展名公开。
（请注意，OpenGL 3.1核心配置文件甚至不存在，Mesa就是这样。在GL 3.2中引入了配置文件。）
这正是glxinfo告诉你的：
OpenGL core profile version string: 3.3 (Core Profile) Mesa 10.6.0-devel (git-ba35393 2015-04-04 utopic-oibaf-ppa)
OpenGL version string: 3.0 Mesa 10.6.0-devel (git-ba35393 2015-04-04 utopic-oibaf-ppa)
